Description for BECKHOFF EL3012 2-Channel Analog Input Terminal

The EL3012 analog input terminal processes signals in the range between 0 and 20 mA. The current is digitised to a resolution of 12 bits and is transmitted, electrically isolated, to the higher-level automation device. The input channels of the EtherCAT Terminal have differential inputs and possess a common, internal ground potential. The EL3012 combines two channels in one housing. Overload condition is detected, and the terminal status is relayed to the controller via the E-bus. The EtherCAT Terminal indicates its signal state by means of light emitting diodes. The error LEDs indicate an overload condition.Technical dataEL3012 | ES3012Number of inputs2 (differential)Power supplyvia the E-busTechnologydifferential inputSignal current0…20 mADistributed clocks–Internal resistancetyp. 85 Ω + diode voltageInput filter limit frequency1 kHzCommon-mode voltage UCMmax. 10 VConversion time0.625 ms default setting, configurable, multiplexResolution12 bit (16 bit presentation incl. sign)Measuring error< ±0.3 % (relative to full scale value)Surge voltage resistance35 V DCElectrical isolation500 V (E-bus/signal voltage)Current consumption power contacts–Current consumption E-bustyp. 130 mABit width in the process imageinputs: 8 byteSpecial featuresactivatable FIR/IIR filters, limit value monitoringWeightapprox. 55 gOperating/storage temperature-25…+60 °C/-40…+85 °CRelative humidity95 %, no condensationVibration/shock resistanceconforms to EN 60068-2-6/EN 60068-2-27EMC immunity/emissionconforms to EN 61000-6-2/EN 61000-6-4Protect. class/installation pos.IP 20/variablePluggable wiringfor all ESxxxx terminalsApprovals/markingsCE, UL, ATEXEx-MarkingII 3 G Ex nA IIC T4 Gc
